We too toured the new Classic at Alumapalooza. The ducted air system is very quiet and the unit itself is simply outstanding. The new a/c design could be a game changer. Unfortunately at $127K+ it won't be for us.

I suppose I can reply to this as my 2015 Serenity 30RB is actually going to production today. And as I sold my Allegro Bus a couple of months ago, I am quite happy about the changes for 2015. However, the price increase is about $4,000 for my unit, so the new models with ducted air are not without some increased expense. Also, about three inches taller due to the "cap" on the roof which is where the ductwork is installed.

More to come once I have taken delivery.

Yeah, but the duct won't increase your overall height. The ac unit and vent covers ( if you install them) will still be taller.

Good to hear it is quieter. I share that this spring when I was with my father looking at Class A coaches we ran the AC on several models- All were ducted. There was quite a difference on sound even between ducted vs. ducted. As far as efficiency goes I cannot imagine that overall cooling is better but perhaps the distribution of cooled air is improved. what does this "CAP" look like?

The pictures on Colonial's YouTube stuff showed registers in the ceiling, probably some return and the rest distribution. Not too hard to visualize all ducting in a new false ceiling with the fan/compressor on the roof, just like you might do in a commercial building.

Yeah, but the duct won't increase your overall height. The ac unit and vent covers ( if you install them) will still be taller.

I too would love to see a drawing of the duct system. I understood that there is a new "hump" on the roof serving as the duct so you don't lose any interior ceiling height. If the ac unit is mounted on top of the hump, it would increase your overall exterior height.

The ducted air allows a bit more headroom due to no A/C hanging down. I suspect the noise issue of pre-2015 units can be mitigated by some clever techniques but the headroom issue would remain. The question is whether the price increase for 2015 wide bodies will be enough so as to allow the used prices of older models to remain steady.

An example is in my unit which with the two A/C's, power porch awning, and basic price increase, is nearly $10,000 more than a 2014 with one A/C and standard awning.

My conclusion is the used prices will remain stable for 2014 and older units, although there may be some transient cuts from dealers in units in stock.

Walked thru a 2015 International 27FB last weekend with a new color scheme. Looks like the Serenity inside, but has a "wood" floor vs. the "woven bamboo" floor. The floor is darker than our 2014 Signature. Cabinets are light, counters are dark. The new ducted air looks very nice indeed. Saw the new See Level monitor panel, nice upgrade there since my Micropulse panel has so far turned out to be a piece of $@#&. New Clarion radio as well. Walked around the outside to determine whether I could see a "hump" on the roof to hold the ductwork. I thought the roof looked a little higher, but not by a lot. It's not an obvious hump from street level.

It is a seriously fine trailer. Not enough to get me to trade in my 2014 just yet. Given the price increases on the 2015, I'm feeling pretty good about the retained value of my 2014 once the dealers finish their annual ritual of blowing out last year's models to make room for the new ones. My dealer doesn't seem to be having any trouble with that process, btw. His lot had more than the usual amount of open space on it as he sells out the 2014's and waits for more of the 2015s to show up.

The service side of the lot, on the other hand, was packed. Lots of folks coming in for service this time of year...including me for more warranty work. My inverter has been imposible to reliably start up (spins up & then shuts down), my micropulse tank monitors still don't work right (ha!) and the front storage door needs another adjustment so that it closes/opens smoothly and still keeps water out when we drive thru the rain. The storage door keeps things dry now after their previous adjustment, but it can be a %&@!# to open and close unless I spray the edge of it with corrosion X. I should probably do that anyway, but I want them to do things right. A properly adjusted door should not be too much to ask, especially on an AS. (Sorry for the off-topic rant.)
